TECHINCAL GASES

In operation since 1920, Rivoira Group supplies atmospheric, process and specialty gases and is a recognized leader in the commercialization of new technologies that bring productivity and environmental benefits to a different industries.

Rivoira is a member company of Praxair, the largest industrial gases company in North and South America, and one of the largest worldwide.

Rivoira Refrigerants offers a wide range of products, services and technical solutions to the Air conditioning and Refrigeration market.

In the refrigeration sector, Rivoiraʼs long standing, well-consolidated partnership with DuPont™ and

Honeywell™ has enabled us to develop extensive knowledge and expertise.

Activities in this field are supported by a network of production and sales centres extending over the entire

National territory , but also abroad, as well as by the “StarCold™ Point” aftermarket network comprised of reliable and professional agents and retailers.

Rivoira Refrigerants offers to the market the most innovative and environmentally friendly solutions for replacing the old generation of refrigerants, which will be subject to the cap and phase down process driven by F-Gas Regulation, effective January 1, 2015.

The most environmentally friendly refrigerant gases sold by Rivoira include DupontTM Opteon® YF DuPont, which replaces HFC R134a in automotive air conditioning, and Honeywell™ Performax LT ® for commercial refrigeration. Honeywell™ Performax LT ® Both sets of gases offers low global warming potential (GWP) and serve as energy-efficient replacement for R-404A and R-507, both of which have a GWP of greater than 2,500 and will soon be phased out in the European Union market.

In response to strict regulations related to the recovery and disposal of old refrigerants, Rivoira also suppliesthe new service called SimplyGreen. The service makes it easier for contractors doing maintenance on old refrigeration and air conditioning systems to access a simplified procedure for the disposal of the recovery of even small quantities of high GWP gases that would be otherwise discharged into the atmosphere.

LUBRIFCANTS

Rivoira Criolube a range of polyoil ester (POE) based synthetic lubricants, has been specially formulated for use in refrigeration and air-conditioning systems in combination with all types of HFC refrigerant fluid (R-134a, R-507, R-404A, R-407C, R-410A) including drop-in mixtures for HCFC R-22, such as Dupont® IsceonTM MO29 (R-422D) and the like.

The lubricants in the Criolube range are suitable for all types of compressor (piston, scroll, screw compressors, etc.) and ensure high protection against wear to all steel and aluminium surfaces and components, thereby contributing to prolonging the service life of the equipment.

Latest generation systems include newly developed compressor technologies and systems designed to take up less space while offering improved performances and higher energy efficiency; however, they work at higher temperatures.

The products in the Criolube line-up have been developed with the aim to meet the widest variety of technological requirements, by offering the most complete and most versatile range of lubricants currently available on the market.

Moreover, they ensure excellent oil/refrigerant solubility, optimal viscosity and chemical/thermal stability characteristics, enabling them to be used over a wide interval of pressures/temperatures.

REFRIGERANTS

When it comes to air conditioning and refrigeration, Rivoira Refrigerants is tasked with continuing a strategic shift from traditional products to those that increase productivity while actually lowering environmental impact. With an enviable domestic track record, Rivoira Refrigerants is building on its success by setting its sights on key markets abroad.

Rivoira Refrigerants supplies a wide range of refrigerants:

HFC refrigerant fluids

The 2037/2000 European Regulation adopted on 1 January 2010, as amended by the 1005/2009 European Regulation, prohibits the sale and the use for maintenance purposes of HCFC refrigerant fluids, due to their non-negligible impact on stratospheric ozone. Among the HCFCs, R-22 is the gas used most widely and still present in a many of the air-conditioning and refrigeration systems installed up until recently. Conversely, the latest systems have been designed to use HFCs (hydrofluorocarbons such as R-134A, R-404A, R-410A, etc.), having no impact on the ozone layer.

Refrigerant fluids HFO-1234yf and HFO-1234ze are characterised by a very low global warming potential (GWP), in keeping with Kyoto protocol provisions.

HFO-1234yf has already been chosen by major car makers to replace R-134a in climate control units.

HFO-1234ze has been proposed as a non-flammable aerosol propellant and expanding agent (foams) but its physical characteristics make it suitable for use as a refrigerant gas for applications at positive temperatures in any situation where non-flammability is a top-priority requirement.

FREECOLD LINE

With its FreeCold Line, Rivoira supplies StarColdTM refillable cylinders for refrigerant gases, in compliance with the European Directive that prohibits the use of non-returnable cylinders for greenhouse effect gases. Furthermore, these containers are lighter and easier to handle than traditional models.

FreeCold cylinders feature a compact design and are safe and easy to use.

SECONDARY REFRIGERANTS

In addition to main refrigernat gases, Rivoira provides a series of other products, such as:

ETHYLEN GLYCOL AND PROPYLENE GLICOL

Heat transfer fluids are used in large refrigeration plants, when the goal is to reduce the refrigerant fluid used in the plant, or when using potentially hazardous gases (ammonia, hydrocarbons, etc.) and, for safety reasons, the circuit containing the refrigerant gas must be kept apart from public areas. Corrosion inhibitors are added to the glycol to prevent the corrosion of any metals that the glycol solution touches.

Common glycol formulas are:

Ethylene glycol: is the most economical fluid, used primarily in heat-exchange applications.

Propylene glycol: less toxic than ethylene glycol, it is recommended for alimentary uses.

Product is available in two types and sizes of packaging: 220 / 230 kg non-returnable kegs. and 1000 kg non-returnable cubes.

For cooling applications, Rivoira Refrigerants has three different types of glycol:

Hydrocarbons are highly flammable gases which, for safety reasons, are mostly used in systems requiring small gas charges. Cooling systems with high gas charges may be constructed, provided that a confined refrigeration station is used mated to a thermal transfer fluid.

The hydrocarbons used most widely in refrigeration applications are:

R-600a (Isobutane for refrigeration) Is used primarily in household refrigerators.

R-290 (Propane for refrigeration) Is used in small store refrigerators, normally working at positive temperatures, and in a few industrial systems requiring negative temperatures.

SOLVOSTAR

SolvoStar” is an azeotropic mixture of pentafluoropropane and dichloroethylene, pressurised with nitrogen.

It is the ideal fluid used to clean refrigeration and air-conditioning system.

Cleaning the cooling circuit is essential to ensure flawless operation of refrigeration systems and A/C circuits. In particular, it is important to use a cleaning agent when a compressor motor burns out, or the retrofi tting of the system calls for the complete elimination of the old lubricant or oil, or when, during scheduled maintenance, we want to remove metal, sludge, or acid oil particles from the circuit.

SolvoStar does not harm the ozone layer and therefore is suitable to replace R-141b and has many important benefits.
